That being said, here's a general overview of the process. This is not a complete, step-by-step guide and variations exist depending on the exact model and trim level of your Bonneville. Always consult a repair manual specific to your vehicle for detailed instructions and torque specifications.
Tools you'll likely need:
* Jack and jack stands (essential for safety)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* C-clamp or caliper compression tool
* Brake cleaner
* Wire brush
* Pliers or caliper piston rewind tool
* New brake pads (ensure they are the correct ones for your vehicle)
* Gloves
* Safety glasses
Front Brake Pads:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Use jack stands to securely lift the front of the car. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Expose the Caliper: You should now see the brake caliper clamping onto the rotor.
4. Compress the Caliper Piston: Use a C-clamp or specialized caliper piston compression tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal.
5. Remove the Old Pads: There are usually pins or clips holding the brake pads in place. Remove these to access and remove the old pads.
6. Clean the Caliper and Mounting Brackets: Use a wire brush and brake cleaner to remove any debris or rust.
7. Install the New Pads: Insert the new brake pads into their respective slots.
8. Reassemble: Reinstall the pins or clips that hold the brake pads in place. Reattach the caliper to the rotor.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Lower the vehicle.
10. Pump the Brakes: Before driving, pump the brake pedal several times to ensure the pads are properly seated.
Rear Brake Pads:
The process for the rear brakes can be slightly different depending on whether your Bonneville has drum brakes or disc brakes. Most Bonnevilles likely had disc brakes in the rear as well. However, the procedure might be more complex than the front brakes, potentially involving:
* Parking Brake Adjustment: The rear calipers often incorporate the parking brake mechanism. You may need to adjust the parking brake after replacing the pads.
* Caliper Slide Pins: Clean and lubricate the caliper slide pins, which allow the caliper to move freely.
Important Considerations:
* Rotor Inspection: Inspect the rotors for wear and tear. If they are excessively worn or damaged, they may need to be replaced or resurfaced.
* Brake Fluid: You may need to bleed the brakes after replacing the pads, especially if you've opened the brake system. Bleeding removes air bubbles that can compromise braking performance.
* Torque Specifications: Always refer to your vehicle's repair manual for the correct torque specifications for lug nuts and other fasteners. Over-tightening or under-tightening can lead to damage.
This information is for general guidance only. Always consult a repair manual specific to your 2000 Pontiac Bonneville for detailed instructions and safety precautions. If you're unsure about any step, seek professional assistance. Faulty brakes can lead to serious accidents.
